That's a 15 lbs discrepancy isn't that a problem? How big of a difference do you look for before you think there's an issue with once of the cylinders?

if they get below 110 lbs then i would probly be thinking about reringing the pistons,do another test make sure you do it the same on each side

I didn't open the throttle when checking, should you? Is opening the throttle going to make the number bigger or smaller
